    Hi guys..
    I'm desperate for some help... my BM keeps completely flattening the battery on random occasions..
    Sometimes it can go over night some times it can last weeks not being driven.
    I was thinking it was something running on after switch off or maybe a loose connection/wire shorting..
    It was checked over and they couldn't find anything ..????
    Its driving me mad.. I've searched for clues high and lo.

    I just jump started it again and took it for a ride to recharge battery.. only this time it has NC written on the heater display???
    Does anyone know what this means ?
    and what could be the cause of my batt prob?

    ETA: it nothing to do with the age of the battery, as I was given a brand new one under warranty, that lasted months before the problem has now started again.

    I,ve read that a dodgy fan can cause this.....think the NC stands for not coded and code is lost when fan goes. Hope this helps.
